Graham and Sibbald has marked its 50th anniversary year by planting 500 trees in Teaghlach Wood, near Comrie, Perthshire.

Ian Gillies, managing partner at the chartered surveyor, said: "We are delighted to be part of this project and feel it shows both our commitment to environmental issues and also our confidence in the future."

Miss Scotland, Sarah Finlay, who is an ambassador for Trees4Scotland, said: "Teaghlach Wood is such a special project and it is just so beautiful up here.

"I think it is great Scottish companies like Graham and Sibbald are supporting tree planting in Scotland."

The Teaghlach Wood project is about to grow even bigger with the establishment of a second phase. The process begins with spraying the bracken before the land is deer-fenced and mounded in preparation for planting the trees.

The trees themselves are planted over the winter months as they are bare rooted saplings. The varieties are all native to Scotland and consist of mainly broadleaf such as oak, willow, birch and rowan.
